Rolling-Horizon Algorithm for Scheduling under Time-Dependent Utility Pricing and Availability

摘要

This work addresses the scheduling of continuous single-stage multiproduct plants withrnenergy intensive processing tasks and time-dependent electricity cost and power supply.rnA new rolling horizon algorithm is proposed that consists of a planning model to predictrnthe production levels and a continuous-time model for detailed scheduling. The resultsrnfrom a set of test problems from the literature show that the algorithm can generaternglobal optimal solutions much more rapidly than standalone discrete or continuous-timernformulations in problems involving unlimited power availability.
